Hi,

I have a question of howto use external variables in the nmap plugin.

I have a simple yml:
plugin: nmap

address: 192.168.10.0/24

…

But I need to pass the network range as a external variable, as example:

plugin: nmap

address: ‘{{ mynetrange }}’

I tested this argument also:

use_extra_vars: true

…

And launch as:
ansible-inventory -i nmap.yml --list -e “mynetrange=192.168.10.0/24”

but I can’t get it to work, someone could help me?

Regards

Could you use the environment variable ANSIBLE_NMAP_ADDRESS as documented below as an alternative?

Inventory plugins can only read from ENV variables. Not sure why, but seems like a architectural limitation. Most of the inventory plugins either read from files (like AWS) or from ENV variables.

The basic configuration items are not templatable at all as no vars
were accessible when designed, extra vars got added later for
'constructed' features.
We do have plans to make this work, specially with vaults (you can
vault the file, but not use inline vaults).
